Lactoferrin is secreted by mammals and displays extensive biological effects including boosting the cold tolerance of a well-applied probiotic strain.

Collagen, Type II (derived from bovine snout cartilage), is a homotrimeric helical protein composed of three identical α1(II) chains and is a major component of animal cartilage. It possesses multiple biological activities, including maintaining cartilage tissue integrity, inducing immune tolerance, and promoting chondrocyte growth and redifferentiation. It is commonly used to induce collagen-induced arthritis (CIA) models and has demonstrated significant efficacy in alleviating pain and inflammation associated with collagen-induced arthritis in mice, making it widely applicable in osteoarthritis-related research.

Conalbumin (ovotransferrin) is an egg white protein and glycoprotein with antimicrobial, antioxidant, and immunomodulatory properties as a member of the transferrin and metalloprotease families. Conalbumin has a binding logarithm of 15 for Fe3+ at pH 7 or higher.

Collagenase Type VIII hydrolyses Type VIII collagen and can be used to study collagen metabolism processes in the pathophysiology of atherosclerosis. Collagenase Type VIII can also hydrolyse other protein components in the extracellular matrix (ECM), making it useful for tissue dissociation and cell separation.

Fibronectin (from bovine plasma) plays pivotal roles in various cellular processes including tissue repair, embryogenesis, blood coagulation, and cell migration/adhesion.

Urokinase peptidolytic,Urokinase-type plasminogen activator (uPA) is a trypsin-like serine protease that exists as an inactive zymogen (pro-uPA) and requires proteolytic cleavage for its activation. once activated, it serves as the central catalyst in a proteolytic cascade that converts plasminogen to plasmin, a process critically involved in physiological and pathological thrombolysis and extracellular matrix degradation.

C1qProtein (human) serves as a subunit in the complement system. It binds to a variety of ligands from self, non-self, and altered-self, contributing to the balance of the immune system, promoting tissue repair, and defending against pathogens.

Hemocyanin, a substantial copper-bearing respiratory protein, serves as a crucial molecule in non-specific innate immune defense, exhibiting phenoloxidase, antiviral, antibacterial, hemolytic, and antitumor activities [1].

Type II collagen (from porcine articular cartilage) is a collagen protein that can stimulate an animal's immune system to produce specific antibodies against this collagen. Additionally, collagen serves as a hydrolysis substrate for MMP.

Type IX collagen (from porcine articular cartilage) is a collagen protein sourced from pig cartilage that can stimulate the immune system in animals to produce specific antibodies against this collagen. Additionally, the protein serves as a hydrolytic substrate for MMP.

Prostate specific antigen protein (human) is a serine protease produced by the prostate epithelium. It is utilized in prostate cancer research.

Deoxyribonuclease II from porcine spleen (DNase II) is a nucleic acid endonuclease primarily located within lysosomes. It cleaves the phosphodiester bond in DNA between the 5'-phosphate and 3'-hydroxyl groups, degrading exogenous DNA and generating nucleoside-3'-phosphate.

Type IX collagen (from bovine articular cartilage) is a highly purified protein that can stimulate the immune system in animals to produce specific antibodies against this collagen. Additionally, collagen acts as a substrate for matrix metalloproteinases (MMP).

Oxidized low density lipoprotein (mouse) is a modified form of low-density lipoprotein (LDL). It induces atherosclerosis (AS) by promoting endothelial dysfunction and accelerating the growth and migration of vascular smooth muscle cells (VSMCs).

9-keto latanoprost is a derivative of Latanoprost, which acts as an agonist of the F-prostaglandin (FP) receptor.

Protein A (SPA) is an immunoglobulin (Ig)-binding protein found on the bacterial surface and can be freely secreted into the extracellular environment. It binds to the Fc region of antibodies and the Fab region of B cell receptors, thereby blocking opsonophagocytosis and inducing B cell death in vitro. Protein A is capable of inhibiting opsonization and phagocytosis in vitro.

Type V collagen (from bovine amnion) is a highly purified form of collagen. It serves as an immunogen capable of inducing the production of specific antibodies in animals. Additionally, this collagen acts as a substrate for MMP hydrolysis.

Brucellabacterialprotein is a natural protein purified from Brucella, used in life sciences research.

Lipase, Candida antarctica (Immobilized) is an immobilized lipase derived from Candida antarctica fraction B. It exhibits high stability and selectivity, making it widely used in chemical synthesis, modification of edible oils, and biodiesel production.

Neutralprotease, Paenibacillus polymyxa (Dispase II, Dispase), is a neutral protease that effectively functions as a fibrinolysin and type IV collagenase. It is utilized to separate intact epidermis from dermis and to detach complete epithelial sheets from the matrix in cultures.

Proteinase K (Protease K) (NGS grade) (EC 3.4.21.64) is a serine protease known for its high enzyme activity and broad substrate specificity. It preferentially cleaves ester and peptide bonds adjacent to hydrophobic, sulfur-containing, and aromatic amino acids at the C-terminal. It is commonly used in protein degradation to produce short peptides. This product is NGS grade, free of Nickase.

Wheat Germ Agglutinin (WGA) is a plant lectin that serves as a probe with specific binding affinity for biomolecules such as polysaccharides and polypeptides. WGA can be utilized as a biomaterial or organic compound relevant to life science research.

Zein is a plant-based protein polymer used to create nanofiber mats through electrospinning. Known for its excellent cell compatibility and ease of preparation, zein is suitable for use in drug delivery systems.
